Had one blacken my eye one night running the lake during a bass tourney. Thought he'd busted my eye until I realized I could roll it around a bit. Two trips to the eye doctor to get all the little leg parts removed and stayed black for nearly a month. That was the night I decided I really didn't want to be a pirate - hate eye patches. Did learn a very valuable lesson about wearing safety glasses when running the water. (we still placed 3rd, by the way)
